In this chapter, the importance of physics and measurement of the quantities are illustrated. Physics is actually the study of the Entire Physical World. To describe the physical world, there are Base Quantities and Derived Quantities. The whole world has adopted the International System of Units. While measuring, some errors occur i.e. Random and Systematic Errors. Two different terms, Precision, and Accuracy are defined in this Chapter. Significant figures, Scientific notation, and Dimensions of Physical Quantities are also discussed in the Chapter. So, this is the best source to get important MCQs online.<\/p>\n<h2 style=\"text-align: center;\">1st Year Physics Chapter 1 Measurement MCQs with Answers<\/h2>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-389 aligncenter\" src=\"https:\/\/talib.pk\/test-preparation\/wp-content\/uploads\/2019\/09\/Physics-1st-Year-MCQs-1.jpg\" alt=\"1st Year Physics Chapter 1 Measurement MCQs with Answers\" width=\"300\" height=\"300\" srcset=\"https:\/\/talib.pk\/test-preparation\/wp-content\/uploads\/2019\/09\/Physics-1st-Year-MCQs-1.jpg 300w, https:\/\/talib.pk\/test-preparation\/wp-content\/uploads\/2019\/09\/Physics-1st-Year-MCQs-1-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<h3>KEY POINTS<\/h3>\n<div class=\"box info  alignleft\" style=\"width:100%\"><div class=\"box-inner-block\"><i class=\"fa tie-shortcode-boxicon\"><\/i>\n\t\t\t\n<div class=\"lightbulb tie-list-shortcode\">\n<ul>\n<li>Physics<\/li>\n<li>Physical Quantities<\/li>\n<li>International System of Units<\/li>\n<li>Errors and Uncertainties<\/li>\n<li>Significant Figures<\/li>\n<li>Precision and Accuracy<\/li>\n<li>Dimensions of Physical Quantities<\/li>\n<\/ul>\n<\/div>\n\t\t\t<\/div><\/div>\n<p><strong><span style=\"color: #ff6600;\">Question#1<\/span>.
